NEW YORK (GenomeWeb) − Researchers in Toronto have developed a method to dissect and sequence DNA from structures within the nucleus of individual cells, allowing them to study the spatial arrangement of genes in great detail.

Scientists formerly employed by electron microscopy sequencing firm Halcyon Molecular have published a method they developed at the company for stretching single DNA strands and placing them on a substrate.

ZS Genetics has started to work on a prototype of its transmission electron microscopy-based DNA sequencer that it hopes to complete next year, followed by the release of a commercial instrument several years later.
